Popular Abstract in German Spannungsgesteuerte Kalziumkanäle haben eine große Bedeutung in vielen elektrisch erregbaren Zellen, wie z.B. in Nervenzellen und pankreatischen beta-Zellen. Hier werden sie folgendermaßen aktiviert: In der Nahrung enthaltener Traubenzucker (Glukose) wird nach einer Mahlzeit über den Blutstrom im Körper verteilt und in die beta-Zellen über Glukosetransporter aufgenommen.Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. Several subtypes of voltage-gated Ca2+ channels are known and the L-type has been found to be the main contri

The work presented in this thesis focuses on developing methods of measuring moisture properties at high moisture levels. Paper I deal with a new method of measuring moisture diffusivity at high moisture levels. Papers II to IV present methods of measuring moisture storage capacity as well as results from such measurements. Paper V evaluates the use of thermal imaging to measure transient moisture

The incidence of Diabetes Mellitus increases globally in epidemic proportions. Type 2 Diabetes is the most prevalent form of Diabetes, comprising 90% of the patients. In Type 2 Diabetes, two processes contribute to the development of the disease: insufficient insulin secretion from the pancreatic ?-cell and insulin resistance of the target organs. This leads to loss of control of blood glucose lev

Hematopoietic stem cells (HSC), the ancestors of all blood cells, have the ability to give rise to mature effector cells through a series of developmental steps. This is a tightly regulated, though a highly dynamic process: on the one hand, dysregulation in steady-state could lead to under- or overgrowth of certain blood cell lineages, whereas, on the other hand, demands for certain mature blood c

This thesis presents methods for improving the accuracy and efficiency of tasks performed using different kinds of industrial manipulators, with a focus on the application of machining. Industrial robots offer a flexible and cost-efficient alternative to machine tools for machining, but cannot achieve as high accuracy out of the box. This is mainly caused by non-ideal properties in the robot joint

Popular Abstract in Swedish Diabetes mellitus är en endokrin sjukdom. Hos friska individer producerar beta och alpha cellerna i bukspottkörteln insulin och glukagon, de viktigaste hormonerna för att reglera blodglukos¬koncentrationen. Insulin utsöndras som svar på förhöjda blodglukosnivåer. Hormonet minskar glukosproduktion från levern och ökar glukosupptaget samt dess användning och lagring i fetType 2 Diabetes (T2D) is a multifactorial disease, which has made it difficult to resolve its pathophysiology. We investigated processes that could contribute to the development of T2D. In addition to well-known hallmarks of the disease, such as defective insulin secretion, insulin resistance and perturbed glucagon secretion, we aimed to find a possible role for CLOCK genes in the pathogenesis of

Popular Abstract in Swedish Lokal läkemedelsstatistik – ett verktyg för att identifiera problemområden och att bedöma effekter av information och utbildning om läkemedel. Det finns behov att studera läkemedelsförskrivning och läkemedelsanvändning och dessas samband med och effekter på hälsa, sjuklighet och överdödlighet. Det är också önskvärt att kunna använda individdata. I Sverige är det i allmAims: 1) To assess if drug sales data indicate differences in morbidity, mortality, socio-economic conditions and deviating prescribing habits among physicians; 2) to identify areas for educational interventions and to analyse changes in prescribing after educational activities. In addition, an effort was made to estimate differences between pharmacy sales and purchases by the population, and the

Brämhults Juice AB is a Swedish company producing fresh juice for the Scandinavian market. Fresh juice is rich in taste but has limited durability and must be treated with special care throughout the whole supply chain. Not only will the quality of the product be affected if mistreated, but there are also contamination risks meaning that people actually could get sick, although the risk is very sm

Surface display in insect cells: Systems available for surface display that utilize bacterial phages are insufficient for displaying a number of eukaryotic proteins. By instead presenting proteins on the surface of eukaryotic cells or virus, some of these problems might be overcome. The baculovirus/insect cell system, which has a high expression rate and post-translational mashinery closely resemb

The design and analysis of specular radar absorbing materials are investigated throughout the dissertation. Although the topic has been investigated for more than 60 years by many researchers and numerous designs have been proposed, still many technical challenges are remained unanswered. The basic questions are, e.g., the optimal thickness of a design, the possibility of utilization of unconventi

Acute myeloid leukemia (AML) is a highly heterogeneous blood disease which is characterized by different mutations and chromosomal rearrangements. Nearly 60% of genetic alterations have been found in AML patients involve in signaling pathways including signaling of tyrosine kinase receptor FLT3. FLT3 mutations emerged as one of the most common mutations in AML which represent around 35% of all AML

Inflammatory airway diseases and lower respiratory tract infections are leading causes of severe illness, disability and death worldwide. Much of today´s hypotheses about the underlying inflammatory processes and pathogenic contribution by immune cells come from in vitro experiments or animal models. As a consequence, our knowledge of the actual immunopathological events in real patient tissues is

Dying in older persons precedes often by a prolonged period of frailty and multimorbidity. The global increase in the aged population means more death at an older age and highlights the need to integrate palliative care in elderly care. Knowledge-based palliative care is lacking outside the specialist units, for which reason there is insufficient access to palliative care for older persons. Thus t

Northern forest ecosystems make up an important part of the global carbon cycle. Hence, monitoring local-scale gross primary production (GPP) of northern forest is essential for understanding climatic change impacts on terrestrial carbon sequestration and for assessing and planning management practices. Here we evaluate and compare four methods for estimating GPP using Sentinel-2 data in order to

Historically, aerosols of anthropogenic origin have offset some of the warming from increased atmospheric greenhouse gas concentrations. The strength of this negative aerosol forcing, however, is highly uncertain-especially the part originating from cloud-aerosol interactions. An important part of this uncertainty originates from our lack of knowledge about pre-industrial aerosols and how many of

Background: In prostate cancer (PCa), questions remain on indications for prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging and PSMA radioligand therapy, integration of advanced imaging in nomogram-based decision-making, dosimetry, and development of new theranostic applications. Objective: We aimed to critically review developments in molecular hybrid imaging an

Land cover governs biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Progress addressing

Phosphorus (P) is a critical macronutrient for plant growth, often limiting plant production in areas where plant demand is higher than soil supply. In contrast to nitrogen (N), P cannot be sourced from the atmosphere; therefore, where it is rare, it becomes a strong constraint on primary production. Due to this, most dynamic global vegetation models (DGVMs) are incorporating a prognostic P cycle

The number of users and the information transmitted over wireless networks have been growing constantly during the last decades. Nowadays, the pace of this growth is extremely sharp because of the new applications which heavily rely on wireless networks to meet users' demands. Wireless networks infrastructures are constantly developing to meet these demands. Massive multiple-input multiple-output
